Bug #3449
Two TVheadend instances -- SAT>IP autodiscovery broken
0%
Description
Hi folks!
My setup is as follows:
- TVheadend on a Rasperry Pi; Jessie; 4.1-1246~gdc4e037
- TVheadend on a Ubuntu; 15.10; 4.1-1246~gdc4e037
- Both are connected via a switch using IPv4; no IPv6 active at all
I want the TVH on my Pi to automatically add the other TVH instance.
Using the upnc trace subsystem, i figured out that the Pi receives the packets from the Ubuntu instance.
The Pi does receive the packet containing the configuration URL http://XXX.XXX.XXX.XXX:9981/satip_server/desc.xml, but it seems that it does not process the packet properly.
No satip server is added to the list of DVB inputs.
If i start the TVH on my Pi using the --satip_xml parameter, everthing works like a charme. The Pi finds the other TVH instances and adds it to its DVB inputs.
This looks like a bug to me, but further debugging needs to be done to narrow the issue down.
Can you pls give me any advice what the next steps are?
Cheers,
flip

Updated by Do you allow the HTTP (WEB) access on the SAT>IP server for the SAT>IP client ? The '--trace httpc' might give you a reason why the desc.xml is not fetched correctly.

Updated by I started TVH using '--trace httpc,upnp,udp,satip -d -S', but there is no output from httpc at all.
The last thing about satip i see in the output is '2015-12-29 12:27:19.855 [ TRACE] upnp: unicast - received data from 192.168.178.xxx:27655 [size=337]'. This is the response from the second TVH instance.
In addition to that, i can manually download the desc.xml file from the TVH on my Ubuntu machine using wget. Therefore, i suppose this is not fw-related.

If i specify the --satip_server parameter, the http client works correctly. I see a lot of debug output telling me that it can successfully talk to my satip server.

No idea, testing two instances on same machine and the upnp discovery works here. It seems related to your network settings.
The satip_discovery_service_received() fcn in satip.c should be called when UDP packet is received and satip_discoveries list should be updated there.

Oh my good. I'm so sorry!
Both TVH instances use the same uuid because i copied the config from one machine to the other....
Therefore, the second TVH wasn't add. :(
I deleted the uuid from the config. That forced the tvh to generate a new one. Voilá. It works!
